Quick maintenance method for double-block ballastless track
The invention discloses a quick maintenance method for a double-block ballastless track. The quick maintenance method comprises a chiseling stage, a transition stage, a pouring stage and a recovery stage. The chiseling stage mainly comprises the steps of chiseling concrete between sleepers, cutting upper-layer reinforcing steel bars of a roadbed slab, milling an inverted arch filling layer and thelike. The transition stage mainly comprises the steps of sleeper beam top pushing removal, wooden sleeper transition, track slope adjustment, steel bar planting and drilling within a reconstruction range and the like. The pouring stage mainly comprises the steps of transition wooden sleeper extraction, sleeper installation, concrete pouring and the like. The recovery stage mainly comprises the steps of regulating tracks on the two sides of a section to be downhill, diffusing and locking a line stress, finely adjusting the tracks, recovering traffic, gradually increasing a speed and the like.According to the method, on the premise that the driving safety is the first place, a defect of skylight point construction time points can be overcome, a damaged road section can be rapidly and orderly repaired and maintained, the precision and safety of the maintained ballastless track are good, a track structure is firm and durable, and the method has positive practical significance in improving safe operation of the railway and prolonging the service life of the railway.
本发明公开一种双块式无砟轨道快速维修方法，包括凿除阶段、过渡阶段、浇筑阶段和恢复阶段；凿除阶段主要包含轨枕间混凝土凿除，道床板上层钢筋切割，仰拱填充层铣刨等步骤；过渡阶段主要包含轨枕梁顶推移除、木枕过渡、轨道调坡、重建范围内植筋钻孔等步骤；浇筑阶段主要包含过渡木枕抽取、轨枕安装、混凝土浇筑等步骤；恢复阶段主要包括整治区段两侧轨道顺坡、线路应力放散及锁定、轨道精调、恢复通车并逐渐提速等步骤；本方法能够在确保行车安全为首位的前提下,避免天窗点施工时间点弊端,快速有序的对病害路段进行整治维修，而且维修后的无砟轨道精度和安全性良好，轨道结构坚固耐用，对于提高铁路安全运营和使用寿命有积极的现实意义。
